How to enable differential signal in stratix 10 transreciver phy IP?

HI,

You can refer to Stratix 10 datasheet to find out the supported differential IO standard for the transcevier channel (depends on Ltile, Htile or Etile)

After that, you can use quartus assignment editor to set the desired differential IO standard for your transceiver refclk and receiver channel pins.

Thanks.
